This invention pertains to the spool dyeing of textile yarnse roving, etc., and more particularly to apparatus so devised as to permit determinationof the progress of the operation' from time to time without necessitating vthe drainage ofthe kettle or vat or prolonged l interruption of the process.

By reason of the many and varying factors involved in textile dyeing, particularly the non-uniform character of the fibre employed as respects its" capacity to absorb dye stuffs and the varying characteristics of the dyes employed, it is substantially necessary7 at intervals during the dyeing process to inspect the material in order to determine the progress of the operation. yWhilesuch inspection is comparatively easy in open kettle or vat dyeing when the yarn is'in the form of hanks which may readily be lifted `from the dye liquor from time to time, it is quite another matter to determine ,the progress of the operation when dyeing yarn by the pressure process upon large and heavy dresser spools or warp beams.

In the practice of the spool or pressure dye-A ing process the kettles usually employed are provided with one or more special apertures or holes at convenient points, such holes being provided withcovers which must irst be removed when a sample is to be taken and then certain quantity of the yarn or thread is pulled ofi' from the spool for inspection.. This mode of sampling is unsatisfactory since the small piece of thread pulled ot from the spool may not be a fair sample of the mass on the `Spool while it frequently involves breakage or snarling of a large amount of yarn and atfbest is slow and diicult to perform. Another method is to place a loose piece of the material in the dye kettle, removl' ing it from time to time-for inspection, but

here again the sample may not be representative of the mass upon the spool since-the mode of application of the dye is quite diiierent in the two cases. f

In accordance with the present invention I provide ready means for removing an entire spool from thedye kettle or vat for sampling purposes, this being accomplished without draining the kettle or stopping the operation 1926. Seria? No. 94,165.

for more than a few minutes. By thus eX# posing the entire spool to view the operator is able to obtain a much more accurate knowledge ofthe progress of the operation than by examination of small and often unrepresentative samples.

When a one spool vat is employed the one spool which carries the yarn is used for sampling but when the vat contains a large numl ber of spools certain selected ones of these spools are arranged for sampling in accordance with my present invention.

In the accompanying drawings I have illustrated a preferred embodiment of the invention as applied to a. multiple spoolfkettle, it being understood that substantially the same arrangement may be used in a one spool kettle.' N Y A In the drawings: p

Fig. 1 is a. vertical'section, with certain parts broken away, illustrating my invention as applied to a dye vat of usual type, the section being substantially on the line 1-1 of Fig. 2; 4

Fig. 2 is a plan view of the device shown in Fig. 1 on a smaller scale and with' certain parts omitted;

Fig. 3 is al Jfragmentary side elevation, partly in section, showing the lower part of the dye kettle, the spools being omitted; and

F ig. 4 is a side elevation to larger scale showing one of the spool supporting sleeves.

Referring to the drawings for a more 'detailed description of the invention, the numeral l designates a dye kettle or vat, here shown as cylindrical, provided with a bottom The vat is also furnished with a false bottom 3 spaced from the bottom 2 to provide a plenum chamber 4.

An outletY conduit 5 opens at a oint 6 (Fig. 2) substantially at the center o the vat and above the false bottom 3, such conduit extending down through the plenum chamber and through the bottom of the vat to the inlet of a circulating pump 7. The outlet of the pump is connected to a delivery conduit 8 which opens at 9 (Fig. 2) into the plenum chamber 4. Preferably the inlet conduit 5 is of a diameter substantially greater 'than 2o4 with a beveled 6r conical surface 16 which the diameter' of the outlet conduit 8 so as to aivoid cavitation at the inlet of the pump.

ing.

Each of the bushings 10 is Afurnished at its open end with an annular fiange 12 resting upon the upper surface of the false bottom 3 and which is adapted to support the lower head 13 of a spool.. As here shown, the spool is provided with a hollow barrel 14 and with an upper head 15, and preferably the upper end `.fof thesleeve 10 is furnished assists in centering the spool when it is placed in the vat. I

The spools employed are furnished with perforatedbarrelsand the yarn mass Y is wound thereon, preferably with an open wind, to facilitate the passage of the dye liquor from the interior of the spool outwardly.

l As ordinarily arranged, each spool is set down into the vat so that its upper headis below the low water level of the dye-liquor and each spool is furnished with a member 17 engaging its upper head.y `This member 17 Aforms a cover for the upper end of the spool barrel and has'a central opening for the passage of arod 19 which is anchored at itslower end bytmeans of a suitable nut or other device and which is screw-threaded at its upper end to .receive a nut 18 by which clamping pressure may bekapplied to the cover member 1 to hold the spool in operative position. .The rod 19 passes up through the corresponding sleeve 10 and through the barrel of the spool,

' and when the spool is clamped in position the cover 17 prevents escape of the dye liquor through the upper end of the spool so that it is constrainedjto pass outwardly through the perforations'in the barrel and out through the yarn mass upon the barrel.

ln qrder to insure uniform dyeing of the yarn upon the spool it is considered necessaryr to maintain the cool or low .level of the dye liquor at .a'point somewhat vabove the upper end of the spool, but when the liquor is heated to the boiling point by the introduction of steam, the level soon rises considerably higher as indicated at W by reason of the condensa'-v ti'on of the steam. Since the usual clamping means comprising the cover 17 and the nut 18 is below the low level,` it is7 impossible to remove a. spool for sampling without first partially draining the vat.

lnwaccordance with the present invention, one f the spools -is furnished with' a special annular cover 2O (Fig. 1) provided with a tubular upwardly extending stem 21.

The stem 21 may or may not be integral with the cover proper as desired.

The lower end ofthe stem 21 is closed by 'means of a plug 22 having a central aperture of a cap 24 fitting snugly therein. 'This cap is furnished with a central aperture for the passage of the upper end of the 'rod 19a the latter being screw-threaded for the reception of a clamping nut 24a. v

When this special sampling spool has been set in place in the vat, the vcover '20 with its sleeve 21 is slipped down over the rod 19L until it bears against the upper end of the spool. The nut 24 is then applied to the upper end of the rod 198L and screwed-down against the cap 24 to apply the desired Clamping pressure to the spool. Whenit is desired to remove the spool for sampling purposes, the

nut 24 may readily be removed from the rod 19tL since it is disposed above the level of the liquid in the kettle. VPreferably though not necessarily I stop the circulating pump for a few minutes while the' spool is being'put in place or is being removed. The cap 2 0 is then lifted and the spool is thus released for removal.

In' accordance .with the' present invention,

I provide means lfor lifting the spool from the 7 dye liquor consisting of a tongs device comprising across bar 25 having arms 26 and 27 pivot-ally secured to its opposite ends. These arms26 and 27 are furnished at their'lower ends with jaws 28 adapted lto engage the flange of the upper head of thespool." 'The tongs is also provided with crossed link members 29 and 30 attached to the opposite ends of the cross bar 25 and these links are connected by a chain 31 adapted to engage a hook 32 forming part of a hoisting tackle 33of any suitable type. Preferably this hoisting tackle is mounted upon atrolley 34 adapted to travel along a rail 35 carried bythe arm 36. of a crane or` other suitable supporting means.

After the spool has been unclamped as above described, the tongs device is lowered into the vat until the jaws 28 engage the'upper l head of the spool; The tongs is then lifted,

thus raising the spool from the ldye liquor.

to permit inspection of the yarn mass thereon. While certain specific arrangements of parts have herein been. shown,- it is to be understood that various modifications and substitutions of equivalents may be made without departing from the spirit of the invention.
